Full Buoyancy model
Hi all,

How to introduce full buoyancy model in CFX 5.5.1. In the documentation it's given that for the full buoyancy model a source term need to be added to the momentum equation (=Thermal expansivity*(den-ref.den)) where in Build form i need to introduce this term?

Thanks, Swapnil

Hi Swapnil, the use of the Boussinesq or the Full Buoyancy model is determined automatically, depending on the setup of your simulation. Mike

Re: Full Buoyancy model
Mike, can you explain to me what thermal expansivity is ? I've looked in some text books but struggle to find it. Cheers Bob
